[jira] [Comment Edited] (CASSANDRA-5836) Seed nodes should be able to bootstrap without manual intervention

    [ https://issues.apache.org/jira/browse/CASSANDRA-5836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16381561#comment-16381561 ]

[~oshulgin] : as I understand it, a bootstrapping node also receives "extra" copies of writes via the storage protocol, which is not technically "streaming in" the data. These "extra" copies do not count towards CL.

While I'm commenting on this ticket, it seems appropriate to share my enthusiasm for resolving the question of the bootstrapping seed nodes. This has been a longstanding point of pain and confusion for operators and those who support them.

> The current logic doesn't allow a seed node to be bootstrapped.  If a user wants to bootstrap a node configured as a seed (for example to replace a seed node via replace_token), they first need to remove the node's own IP from the seed list, and then start the bootstrap process.  This seems like an unnecessary step since a node never uses itself as a seed.
> I think it would be a better experience if the logic was changed to allow a seed node to bootstrap without manual intervention when there are other seed nodes up in a ring.
